网络管理中的一种分级告警关联方法

提出了一种基于ＳＮＭＰ网络管理环境、使用分布式智能代理进行单个网络设备告警关联的算法。算法分成三步：①智能代理驻留在设备本地，对设备发出的告警进行分类，作为协议故障模型有限状态机的输入，产生ＴＣＰ／ＩＰ协议实体的当前状态；②按照服务关系，将状态不正常的协实体关联起来；③对关联的结果赋予一个信念，报告给网络管理中心。该算法将告警关联和故障标识的难度进行了分解，有利于实现网络的实时管理和自动管理。

A Hierarchical Alarm Correlation Method in Network Management

An alarm correlation algorithm using distributed intelligent agents in a SNMP network management environment is proposed. The algorithm can be divided into three steps: (1) classify the alarms emitted by a network device, and input the results to the simple finite state machines (FSM) of TCP/IP protocol entities in order to establish the next state of the entities. (2) using serving relations, correlate the protocol entities whose current states are abnormal. (3) add a belief to the correlation result and then report it to the network management center. This algorithm is of great benefit to realize real time and automated network management.
